Clément Vasseur has released an AirPlay client application for iOS device users. Although the AirPlay technology built into iOS 4.2 allows iOS users to stream content to an AirPlay client device, iOS 4.2 does not currently provide any way to view content from an AirPlay source.
AirView is a free universal application for the iPhone, iPod touch and iPad that allows a device to receive and display AirPlay video streams from another AirPlay-enabled source such as iTunes or another iOS device. Users can simply launch the Airview application on their iOS device which will then appears in a list of AirPlay destinations on other devices.
At this time, AirView supports only video streams and not audio or photos. AirView requires iOS 4.2 and is available from the App Store as a free download.
